This is a set of lists of ships of the United States Navy, including both past and present vessels. In many cases a name will have been used for multiple ships over the years. The annotations following the names are dates for older ships and hull numbers for newer ones.
For most initial letters, this page only lists current ships, with links to lists of all ships, past and present.

The U.S. Navy maintains its official list of ships past and present at the Naval Register, although it does not include early vessels. The Dictionary of American Naval Fighting Ships includes much detail on historical ships, and was used as the basis for many of Wikipedia's ship articles.
